John 1:26

I baptize - He did not deny it; nor did he condescend to state his authority. That he had given. He “admitted” that he had introduced an important “change” in the rites of religion, and he goes on to tell them that this was not all. Greater and more important changes would soon take place without their authority. The Messiah was about to come, and the “power” was about to depart from “their” hands.

There standeth one - There is one.

Among you - In the midst of you. He is undistinguished among the multitude. The Messiah had already come, and was about to be manifested to the people. It was not until the next day John 1:29 that Jesus was manifested or proclaimed as the Messiah; but it is not improbable that he was then among the people that were assembled near the Jordan, and mingled with them, though he was undistinguished. He had gone there, probably, with the multitudes that had been drawn thither by the fame of John, and had gone without attracting attention, though his real object was go receive baptism in this public manner, and to be exhibited and proclaimed as the Messiah.

Whom ye know not - Jesus was not yet declared publicly to be the Christ. Though it is probable that he was then among the multitude, yet he was not known as the Messiah. We may hence learn:

1. That there is often great excellency in the world that is obscure, undistinguished, and unknown. Jesus was near to all that people, but they were not conscious of his presence, for he was retired and obscure. Though the greatest personage ever in the world, yet he was not externally distinguished from others.
2. Jesus may be near to men of the world, and yet they know him not. He is everywhere by his Spirit, yet few know it, and few are desirous of knowing it.
